HTML

Details

As of 29 March 2023, the UK COVID-19 alert level system has been suspended.

The suspension of the system reflects the transition to Living with COVID-19, which is thanks to the ongoing success of the vaccination programme and the availability of treatments for those who need them.

UK Health Security Agency (UKHSA) continues to track the latest COVID-19 epidemiology through numerous surveillance systems, including the weekly National flu and COVID-19 surveillance reports.
